I have a simple down draft box made of 2x6s and connected it to my Delta dust collector. After hours of carving it stays fairly clean inside. I think adding a dust collector and down draft to the CW is important. Wood shops typically have a dust collection for their woodworking tools and the CW is another woodworking tool...except dust collection is EVEN more important with the CW.
